Gapless ferrite structure for circulator or isolator

A gapless ferrite structure for circulator or isolator, comprising:

• a first base, comprising a first flange disposed on an inner wall surface of the first base and a first limit slot surrounded by the first flange;
• a second base, assembled with the first base to form an internal space, and comprising a second flange disposed on an inner wall surface of the second base and a second limit slot surrounded by the second flange;
• a ferrite, with two ends accommodated in the first limit slot and the second limit slot respectively;
• two limit magnets, installed on the first base and the second base respectively and configured to be corresponsive to the ferrite for generating an attraction force on the ferrite;
• and
• two sealing units, configured between an end of the ferrite and the first limit slot and between the other end of the ferrite and the second limit slot respectively,
• wherein an outer wall surface of each of the first base and the second base is respectively provided with an outer groove for individually accommodating each of the two limit magnets.
